In one embodiment, a server maintains a plurality of fax messages associated with a user. Each fax message of the plurality of fax messages has a state that indicates at least a status of read or unread for the fax message. A HTTP connection is established between the server and a phone that serves as a client through which the plurality of fax messages are viewable. States of one or more fax messages are identified at the server and at the phone that serves as the client. One or more synchronization actions are performed, using the HTTP connection, to synchronize the one or more fax messages at the server and the one or more corresponding fax messages at the phone that serves as the client.
